摘　　要：研究了应用于红外光学遥感器的大口径RC光学系统的视场校正镜设计与主镜F#之间的关系,以及后工作距与主镜F#之间的关系。对五种不同主镜F#的RC加校正镜系统进行计算比较,结果表明在像质优良的前提下,主镜F#减小,系统后工作距缩短,视场校正镜越难于设计。In order to enlarge the effective field, field correctors were introduced into the R-C system. The relationship among the field corrector, focal ratio of the primary mirror and the back focal length are discussed. Five sets of correctors were designed for various F^# of the primary mirror of the RC system： F/1.1, F/1.5, F/1.8, F/2, F/2.5. The results show that with the decrease of the focal ratio of the primary the design difficulty of the field corrector shall be increased.
